Babbo Ristorante e Enoteca often uses its Twitter account to inform more than 7,000 followers about last-minute availability, but rarely with the urgency suggested by all capital letters.

A call to the restaurant’s reservation line Sunday confirmed that tables were available throughout the evening, due largely to hurricane-related cancellations.

But New Yorkers are a tough breed. There are few things, including a citywide mass-transit shutdown, that can keep them from a coveted reservation.

Per Se, the Columbus Circle satellite of Thomas Keller’s French Laundry, was still serving oysters and pearls on Sunday night. The restaurant’s receptionist said things remained fully reserved for dinner, with a menu that included Tsar Imperial caviar and an herb-roasted lamb.

Diners may be more skittish about venturing out once Sandy brings heavy rains on Monday, just in time to wreck dinner. According to reservation-booking website OpenTable.com, a prime 7:30 p.m. seating at Perse was still available for Monday night (as of now).

“Due to the storm, there will be a limited menu served on Monday. There is currently availability for dinner reservations on Monday due to cancellations,” Gerald San Jose, a spokesman for the restaurant, said in an email.

Likewise, Torrisi Specialties on Mulberry Street, which is known to fill its very few tables months in advance, remained booked solid for Sunday night. The restaurant made the decision to shut down on Monday evening.

There won’t be any hurricane-enabled steak dinners at Peter Luger’s, the venerable institution on the Brooklyn side of the Williamsburg Bridge. On most nights, last-minute reservations might be available for the very early bird, but on Sunday the steak house shut its doors early.

“We are just about closing,” Valerie Zuckerman, the woman who handles reservations, said at 6:30 p.m. “I’m not sure if we’ll be open on Monday.”
